column header in syncfusion grouping control

[Prem]

How do I get rid of the white line in the column
header cell which ends up truncating the
column header text in the syncfusion grouping control.
I am using version 4.1.0.50

thanks,

Hi Prem,

Please try the code below in the TableControlDrawCell event of the gridgroupingcontrol, to resolve this. In this event handler, draw a line on top of the column header cell.

private void gridGroupingControl1_TableControlDrawCell(object sender, GridTableControlDrawCellEventArgs e)
{
    GridTableCellStyleInfo info = e.Inner.Style as GridTableCellStyleInfo;
    if( info.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell ) 
    {
	e.Inner.Renderer.Draw(e.Inner.Graphics, e.Inner.Bounds, e.Inner.RowIndex, e.Inner.ColIndex, e.Inner.Style);	
	e.Inner.Cancel = true;

	Pen yPen = new Pen(SystemColors.Control);
	yPen.Width = 1.5f;
	e.Inner.Graphics.DrawLine(yPen,e.Inner.Bounds.Location, new Point(e.Inner.Bounds.X + e.Inner.Bounds.Width, e.Inner.Bounds.Y));
    }
}

Let me know if this helps.
Thanks,

Hi Rajagopal,
This did not work - I still see the white line which truncates the column header text when it wraps around. Also, the code you sent seems to draw a system color line - I guess I want to get rid of the existing white line.

Thanks,

Hi Prem,

Please try setting the Buttons3D property to false.

this.grid.TableModel.Properties.Buttons3D = false;

Let me know if this helps.

Hi Haneef,
That did not work - the text still gets truncated. Just curious if this is a known bug.

thanks,
Prem

Hi Prem,

Sorry for the inconvenience caused.

We tried to reproduce this in 4.2, but could not get this issue. Maybe I am not following the steps that you are doing. Attached sample working fine here. Can you post a sample showing this problem or tell us how to see it in the Browser sample/attached sample?

Here is a sample.

Thanks for your patience.

Hi Haneef,
First of all, I am using version 4.1.0.50.
In the sample you provided - after you run the application - reduce the width of the "ParentName" column - the column header text wraps around as expected but the top few pixels
of the letter "P" in the word "Parent" gets truncated.

Thanks,
Prem

style.Text = string.Empty;

//Draw the ColumnHeader Without Text
e.Inner.Renderer.Draw(e.Inner.Graphics,e.Inner.Bounds,e.Inner.RowIndex,e.Inner.ColIndex,style);

//for Formatting the Text in columnHeader

format.Trimming = e.Inner.Style.Trimming;

//for SortTriangle
Rectangle rect = e.Inner.Bounds;
rect.Width -= 10;

//Draw the Text in a ColumnHeader cell.
e.Inner.Graphics.DrawString(Text,e.Inner.Style.Font.GdipFont,new SolidBrush(e.Inner.Style.TextColor),rect,format);
}
